Description

[Technical field]

[0001] The present invention relates to radiation protection clothing, and in particular to radiation protection clothing worn by examiners performing various catheter examinations and treatments of the circulatory system and extracerebral system, or by surgeons such as doctors, nurses, and technicians performing these surgeries. [Background technology]

[0002] Radiation protection clothing has been known for some time now that is worn by examiners performing various catheter examinations and treatments of the circulatory system and neuroexternal system, or by surgical personnel such as doctors, nurses, and technicians performing these surgeries (hereinafter collectively referred to as "users") (see, for example, Patent Document 1).

[0003] To prevent health damage caused by radiation exposure, these radiation protection suits are made using radiation shielding sheets such as polyvinyl chloride resin that contains lead, which has high shielding properties, and each suit is very heavy, weighing 2 to 4 kg. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 5758623 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, the radiation protective clothing disclosed in the above-mentioned prior art is designed to ensure stability around the user's waist, including the pelvis, by the engagement position of the top and bottom three-tier hook-and-loop fasteners, particularly the bottom-most hook-and-loop fastener.

[0006] However, with the radiation protection clothing disclosed in the above-mentioned prior art, the weight (load) as described above is also applied to the shoulders, and combined with the long wearing time, there was a demand for a way to reduce the work burden.

[0007] The object of the present invention is to provide a radiation protection garment which reduces the excessive load placed on the shoulders of the user and also reduces the contact area between the user's shoulders and the fabric, thereby reducing the discomfort caused by chafing. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention provides a radiation protection garment comprising a rear body section that covers the back of the user's body when worn, and left and right body sections that overlap and cover the front of the user's body when worn, the lower parts of the left and right outer edges of the rear body section and the lower parts of the inner edge of the left body section and the lower parts of the inner edge of the right body section being joined together as joining edges, and the parts above the lower parts are unjoined recessed edges when worn, forming shoulder openings through which the user's arms pass. The garment comprises a pair of male and female fixed hook-and-loop fasteners arranged on the left and right inner sides of the rear body portion and shaped like bands extending in the vertical direction, a pair of male and female free hook-and-loop fasteners extending in the vertical direction and engaging with the fixed hook-and-loop fasteners respectively to movably hold the band-shaped waist belt in the vertical direction, and a ring-shaped hollow tube spanning each of the inner sides from the non-joined concave edge portion of the rear body portion to the non-joined concave edge portion of the left body portion, and from the non-joined concave edge portion of the rear body portion to the non-joined concave edge portion of the right body portion.

[0009] The waist belt is height-adjustable independently of the left and right front body panels, so the weight load can be stably supported by the user's waist after the height adjustment. Also, even if the only contact with the user's shoulders is the hollow tube, the entire load can be concentrated on the waist belt, so excessive load on the user's shoulders will not dig in, even if the contact area is small.

[0010] This prevents the fabric from coming into contact with the user's shoulders, thereby preventing the fabric from coming into contact with the shoulders and causing chafing. Effect of the Invention

[0011] According to the present invention, it is possible to reduce the excessive load applied to the user's shoulders and also to reduce the contact area between the user's shoulders and the fabric, thereby reducing the discomfort caused by chafing. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Next, a radiation protective garment according to one embodiment of the present invention will be described with reference to the drawings.

[0014] As shown in Fig. 1, the radiation protective clothing 1 comprises a back body section 10 that covers the back of the user's body (see symbol P in Fig. 4) when worn, a left front body section 20 and a right front body section 30 that overlap and cover the front of the user's body when worn, a waist belt 40, and a hollow tube 50. The radiation protective clothing 1 constitutes a radiation protective clothing main body 2 when the waist belt 40, hollow tube 50, and a free surface fastener 14 described later are removed.

[0015] In this embodiment, "left front" and "right front" do not mean the "left front" and "right front" layers that are different for men and women in Western clothing, but rather mean the front side of the human body when wearing the clothes. Also, "left and right" are based on the left (hand) side and the right (hand) side of the human body when wearing the clothes. Furthermore,

[0016] 2, in the radiation protective clothing main body 2, the back body part 10 and the left front body part 20 are joined by sewing or the like at the lower part of the left outer edge part 10a of the back body part 10 and the lower part of the inner edge part 20a of the left front body part 20, which are joined at the joining edges 10c, 20c, respectively. Similarly, the back body part 10 and the right front body part 30 are joined by sewing or the like at the lower part of the right outer edge part 10b of the back body part 10 and the lower part of the inner edge part 30a of the right front body part 30, which are joined at the joining edges 10d, 30d, respectively.

[0017] In addition, the upper part of the left outer edge 10a of the back body part 10 and the upper part of the inner edge 20a of the left front body part 20 form arc-shaped unjoined recessed edges 10e, 20e, which are not joined together to form a left shoulder opening 3 (hereinafter also simply referred to as "shoulder opening 3") through which the left arm of the user P passes when wearing the garment. Similarly, the upper part of the right outer edge 10b of the back body part 10 and the upper part of the inner edge 30a of the right front body part 30 form arc-shaped unjoined recessed edges 10f, 30f, which are not joined together to form a right shoulder opening 4 (hereinafter also simply referred to as "shoulder opening 4") through which the right arm of the user P passes when wearing the garment.

[0018] The back body portion 10 comprises a lining 11 that is located on the inside (inner side) of the user P when worn, and an outer fabric 12 that is located on the outside of the user P when worn. The left front body portion 20 comprises a lining 21 that is located on the inside of the user P when worn, and an outer fabric 22 that is located on the outside of the user P when worn. The right front body portion 30 comprises a lining 31 that is located on the inside of the user P when worn, and an outer fabric 32 that is located on the outside of the user P when worn.

[0019] With the left front body section 20 joined to the left side of the above-mentioned back body section 10 and the right front body section 30 joined to the right side of the back body section 10 by sewing, the entire outer peripheral edge (except for a portion) is hemmed, which also serves as reinforcement, by sewing, etc., using an edging tape 5 made of an appropriate material such as a synthetic resin sheet.

[0020] It is preferable to use a durable and water-repellent material (e.g., #240 Tefox) for the linings 11, 21, 31 and the outer fabrics 12, 22, 32 of the back body section 10, the left front body section 20, and the right front body section 30. In addition, a radiation shielding sheet (not shown) such as a polyvinyl chloride resin containing lead or the like with high shielding properties is provided as an intermediate layer between the outer and inner fabrics to prevent health damage caused by radiation exposure.

[0021] In this embodiment, the radiation shielding sheet has a lead equivalent of 0.25 mmPb (0.125 mmPb x 2 sheets) for the left front body part 20 and the right front body part 30, because they are two layers when worn, and a sheet equivalent to 0.125 mmPb is used for the back body part 10. The unit "mmPb" indicates the performance of the radiation protective clothing 1 and is a unit that indicates the shielding ability equivalent to a lead plate having a thickness of several millimeters. The above values ​​are merely examples and can be changed as appropriate depending on the purpose of use, such as the type of treatment (for example, 0.175 x 2 sheets = 0.35 on the front side and 0.175 on the back side).

[0022] The lining 11 of the back body portion 10 is provided with a pair of band-shaped fastening hook-and-loop fasteners 13 extending vertically along the left outer edge portion 10a and the right outer edge portion 10b.

[0023] The pair of fixed hook-and-loop fasteners 13 are sewn to the lining 11 by sewing or the like, and have either a male or female engaging surface action. The pair of fixed hook-and-loop fasteners 13 are capable of engaging with a band-shaped free hook-and-loop fastener 14 having the other of either a male or female engaging surface action.

[0024] The pair of free surface fasteners 14 can be engaged and disengaged independently of the fixed surface fasteners 13, and in this embodiment, the free surface fasteners 14 are slightly larger than the fixed surface fasteners 13 in both length in the up-down direction and width in the left-right direction. The top ends of the free surface fasteners 14 may be sewn to the lining 11, for example.

[0025] An upper tier side fastener 23, a middle tier side fastener 24, and a lower tier side fastener 25, each having either male or female engagement surface characteristics, are provided at three appropriate positions on the upper and lower sides of the lining 21 of the left front body portion 20 toward the outside.

[0026] In addition, on the inside of the outer fabric 32 of the right front body portion 30, at two appropriate positions above and below, there are provided an upper stage attached side fastener 33 and a lower stage attached side fastener 34 which have either male or female engagement surface characteristics with respect to the upper stage attached side fastener 23, the middle stage attached side fastener 24 and the lower stage attached side fastener 25.

[0027] The lower tier mounted side surface fastener 34 has a height and width that allows engagement with the middle tier mounted side surface fastener 24 and the lower tier mounted side surface fastener 25. The lower tier mounted side surface fastener 34 may be divided into upper and lower portions so as to be paired with the middle tier mounted side surface fastener 24 and the lower tier mounted side surface fastener 25, respectively.

[0028] The upper edge 18 of the back body portion 10 has an arc-shaped neck edge 18a in the center, and on either side thereof are a left shoulder edge 18b as the upper left edge and a right shoulder edge 18c as the upper right edge.

[0029] The left shoulder edge 18b is inseparably joined to the upper edge 28b of the left front body portion 20 by sewing or the like as a joining member. Similarly, the right shoulder edge 18c is inseparably joined to the upper edge 38c of the right front body portion 30 by sewing or the like as a joining member.

[0030] The neck of the radiation protection clothing 1 (for example, neck edge 18a) does not have a raised collar like that of Western clothing, and the edge shape of the entire neck is designed so that when the radiation protection clothing 1 is worn, it overlaps in a loofah-collared state, as is called in kimonos, as shown in Figure 3. This makes it easy to put on and take off the radiation protection clothing 1. Although the design of the neck (neck) does not have a raised collar as described above, it may be designed so that the left front body part 20 and the right front body part 30 overlap with approximately the same width, for example, in a side-open stand-up collar (medic collar).

[0031] On the other hand, the linings 11 and 21 are provided with a pair of non-joined recessed edges 10e and 20e, and the tube-receiving cylindrical portions 19a and 29a are provided along these. Similarly, the linings 11 and 31 are provided with a pair of non-joined recessed edges 10f and 30f, and the tube-receiving cylindrical portions 19b and 39b are provided along these.

[0032] In addition, the linings 11 and 21 are provided with a pair of joint edges 10c and 20c, and an extension tube housing cylindrical portion 19c, 29c is provided along the pair of joint edges 10c and 20c. Similarly, the linings 11 and 31 are provided with a pair of joint edges 10d and 30d, and an extension tube housing cylindrical portion 19d, 39d is provided along the pair of joint edges 10d and 30d.

[0033] (Waist belt) The waist belt 40 is in the form of a belt that is held between the fixed and free surface fasteners 13 and 14 by the fixed and free surface fasteners 13 engaging with each other near the center of its length (any position depending on the user P). This allows the wearing height of the waist belt 40 to be adjusted in the length direction (height direction) between the fixed and free surface fasteners 13 and 14. Note that the "waist" of the waist belt 40 does not mean the medical "waist" but includes a broader area such as the entire waist including the pelvis (hereinafter also referred to as the "waist" or "waist of the human body"). The waist belt 40 can be adjusted not only in the height direction but also in the left-right direction strictly speaking.

[0034] The waist belt 40 is a long belt extending in the left-right direction when worn, and its length is, for example, longer than the average waist circumference of an adult male.

[0035] In this embodiment, for example, when radiation protective clothing 1 is prepared in multiple sizes taking into consideration sizes (S / M / L, etc.) conforming to Western clothing, etc., a size shorter than the overall left and right width of the radiation protective clothing 1 is prepared. Here, in this embodiment, the left front body part 20 and the right front body part 30 are set to be approximately the same width, but if one of them is shorter in width, for example, if the width of the left front body part 20 that is on the front (outside) when overlapped is narrower than the width of the right front body part 30, the radiation protective clothing 1 may be the same as or longer than the overall left and right width.

[0036] An operating side fastener 41 having either male or female engagement surface characteristics is provided on the inner surface side (body contact surface side) of the waist belt 40 near one end. Also, an operated side fastener 42 having either male or female engagement surface characteristics with respect to the operating side fastener 41 is provided on the outer surface side (non-body contact surface side) of the waist belt 40 at least near the other end.

[0037] As a result, the user P wraps the operating surface side closer to one end around the waist of the body while wrapping the operated surface side closer to the other end around the waist of the body, and then fastens the waist of the body by engaging the operating side fastener 41 with the operated side fastener 42.

[0038] The operated side fastener 42 may be provided across substantially the entire length of the waist belt 40. In this case, by making the engaging surface action different from the male and female of the fixing hook-and-loop fastener 13, it is possible to improve the temporary fastening effect and holding strength when adjusting the height of the waist belt 40.

[0039] (Hollow tube) The hollow tubular body 50 is a long hollow resin tube, and is held by the radiation protection clothing body 2 with its central portion formed in a ring shape (loop shape).

[0040] Specifically, the hollow tube 50 is annular and spans the inner surface (lining side) of each of the non-joined recessed edge portion 10e of the back body portion 10 to the non-joined recessed edge portion 20e of the left front body portion 20, and the non-joined recessed edge portion 10f of the back body portion 10 to the non-joined recessed edge portion 30f of the right front body portion 30. The hollow tube 50 is held in the tube storage cylinders 19a, 29a and 19b, 39b, by penetrating therethrough.

[0041] The hollow tube 50 has extended hollow tubes 51 integrally formed at both ends thereof, which respectively follow the left joining edge 10c of the rear body portion 10 and the joining edge 20c of the left front body portion 20, and the right joining edge 10d of the rear body portion 10 and the joining edge 30d of the right front body portion 30.

[0042] The extension hollow tube 51 is inserted (or penetrates) into the extension tube storage cylinders 19c, 29c and 19d, 39d, and is held therein. This allows the extension hollow tube 51 to be positioned along the lower part of the user P from the armpits (see FIG. 4), allowing the user P to maintain a good posture and prevent fatigue.

[0043] The hollow tube 50 is a hollow resin tube with a diameter of about 5 mm to 10 mm. The resin material is mainly polyurethane, but is not particularly limited to polyolefin or fluorine-based resin, etc., as long as it is flexible enough to not be crushed by the load when it touches the shoulder and to be easily bent into a loop when replacing it.

[0044] In this way, the radiation protective clothing 1 in this embodiment is donned by fastening the waist belt 40 around the waist of the user P, engaging the upper stage mounting side fastener 23 with the upper stage mounted side fastener 33, and engaging the middle stage mounting side fastener 24 and the lower stage mounting side fastener 25 with the lower stage mounted side fastener 34.

[0045] At this time, as shown in Fig. 4, the hollow tube 50 is present on the shoulder of the user P. As a result, for example, in the vicinity of the left shoulder shown in Fig. 4, the periphery including the sewn portion between the left shoulder edge 18b and the upper edge 28b can be separated from the vicinity of the shoulder of the user P by a space H equivalent to the outer diameter of the hollow tube 50 (taking into account deformation in the radial direction [crushing direction]). At this time, a gap can be generated between the shoulder of the human body and the fabric, and air can be let in and out from the neck side of the human body, which contributes to measures against heat when wearing the garment.

[0046] Therefore, when the user P works, the weight of the radiation protection suit 1 is concentrated on the waist belt 40, and the weight is less likely to be applied to the shoulders of the user P. Moreover, since only the hollow tube 50 is in contact with the shoulders of the user P, friction with the linings 11, 21 can be suppressed.

[0047] Here, although the position of hollow tube 50 will depend on how the user P is dressed, as shown in FIG. 5, if it is positioned near the acromion, a bone near the shoulder where there is less muscle, interference between hollow tube 50 and the muscles near the clavicle can be reduced, further contributing to reducing stress during work.

[0048] In this manner, the radiation protective clothing 1 comprises a rear body portion 10 that covers the back surface of the user P's body when worn, and a left front body portion 20 and a right front body portion 30 that overlap and cover the front surface of the user's body when worn. The lower portions of the left outer edge portion 10a and the right outer edge portion 10b of the rear body portion 10, the lower portions of the inner edge portion 20a of the left front body portion 20, and the lower portions of the inner edge portion 30a of the right front body portion 30 are joined to each other as joining edges 10c, 20c, 10d, and 30d, respectively, and the upper portions of the lower portions are non-joined recessed edges 10e, 20e and non-joined recessed edges 10f, 30. The garment has shoulder openings 3, 4 through which the wearer's arms are passed, a pair of male and female fixed hook-and-loop fasteners 13 in the form of a belt extending in the vertical direction, provided on the left and right sides of the inner surface of the back body portion 10, a pair of male and female free hook-and-loop fasteners 14 in the form of a belt and engaging with the fixed hook-and-loop fasteners 13, respectively, to movably hold the belt-like waist belt 40 in the vertical direction, and an annular hollow tube 50 spanning the inner surfaces from the non-joined recessed edge 10e of the back body portion 10 to the non-joined recessed edge 20e of the left front body portion 20, and from the non-joined recessed edge 10f of the back body portion 10 to the non-joined recessed edge 30f of the right front body portion 30.

[0049] On the other hand, a heavy radiation shielding sheet is provided between the lining 11, 21, 31 and the outer fabric 12, 22, 32. This makes the total weight of the radiation protection suit 1 heavy (2 to 4 kg depending on the size, etc.), and in some cases, when performing cardiac catheterization, the person in charge may need 3 to 4 hours for one treatment, and if several treatments are performed in one day, the person in charge must wear the radiation protection suit 1 from morning until night, which means considerable hard work.

[0050] For this reason, it is desirable to avoid concentrating the weight load of the radiation protective clothing 1 on the shoulders of the user as much as possible. In this embodiment, the radiation protective clothing 1 is provided with a waist belt 40 to concentrate the excessive load on the waist of the user, and the hollow tube body 50 is used to minimize the contact area with the user's shoulders, thereby reducing the load on the user's shoulders while preventing chafing and ensuring breathability, thereby reducing the workload.

[0051] Furthermore, by reducing the contact area and suppressing friction, it is possible to make the shoulder (arm) easier to move, which not only improves workability but also makes it easier to stretch the shoulder (arm) during treatment, for example. It also contributes to reducing stress for the user.

[0052] The embodiments of the present invention have been described above in detail with reference to the accompanying drawings. However, it goes without saying that the scope of the technical idea of ​​the present invention is not limited to the embodiments described here. It is clear that a person having ordinary knowledge in the technical field to which the present invention belongs can make various changes, modifications, combinations, etc. within the scope of the technical idea of ​​the present invention described in the claims. Therefore, the technologies subsequent to these changes, modifications, combinations, etc. naturally belong to the scope of the technical idea of ​​the present invention.

[0053] (1) Example of a device that can be connected and disconnected 6 shows a modified example of the joining structure near the shoulder of the human body between the rear body part 10 and the left front body part 20 in the radiation protective clothing main body 2. Although not shown in the figure, the joining structure near the shoulder of the human body between the rear body part 10 and the right front body part 30 is also the same.

[0054] In this example, the left shoulder edge 18b and the upper edge 28b of the rear body portion 10 and the left front body portion 20 are overlapped near the shoulder of the body, and the two are configured to be engageable with hook-and-loop fasteners of different genders (not shown).

[0055] In this way, the left shoulder edge 18b of the back body portion 10 and the upper edge 28b of the left front body portion 20 (and the right shoulder edge 18c of the back body portion 10 and the upper edge 38c of the right front body portion 30) can be joined together and detached via a joining member (hook and loop fastener).

[0056] This makes it possible to appropriately adjust the loop shape of hollow tube 50 in the smaller diameter direction, for example, to accommodate differences between men and women in the thickness of the shoulders in the front-to-back direction.

[0057] (2) Example of non-contact 7 shows another modified example of the joining structure near the shoulder of the human body between the rear body part 10 and the left front body part 20 in the radiation protective clothing main body 2. Although not shown in the figures, the joining structure near the shoulder of the human body between the rear body part 10 and the right front body part 30 is also the same.

[0058] In this example, near the shoulder of the body between the rear body portion 10 and the left front body portion 20, the left shoulder edge portion 18b and the upper edge portion 28b are spaced apart and not in contact with each other, and only the hollow tube body 50 is in contact with the shoulder.

[0059] In this way, the left shoulder edge 18b of the back body portion 10 and the upper edge 28b of the left front body portion 20 (and the right shoulder edge 18c of the back body portion 10 and the upper edge 38c of the right front body portion 30) can also be non-jointed edges that are not joined to each other across the entire left and right width.

[0060] This makes it possible to appropriately adjust the loop shape of the hollow tube 50 in the large diameter direction to accommodate differences in the front-to-back thickness of the shoulders of the human body between men and women, for example, and also makes it possible to further suppress rubbing with the linings 11, 21, 31 near the shoulders.

[0061] (3) Separate type Fig. 8 shows a radiation protective clothing 1 divided into an upper garment 2A and a lower garment 2B. In this example, the length of the upper garment 2A is shorter than that shown in Figs. 1 and 2, and the lower garment 2B is configured in a wrap-around skirt shape. Note that the upper garment 2A differs in length from the radiation protective clothing 2 and there are accompanying modifications, but since the functions according to this embodiment are substantially the same, the same reference numerals are used and specific explanations are omitted.

[0062] In addition, other than the separate type described above, the present invention can also be applied to various types of known radiation protection clothing 1, such as an apron-like configuration.

[0063] Although not specifically illustrated, the present invention can be implemented with various modifications without departing from the spirit and scope of the present invention. [Explanation of symbols]
